Multiple Linear Power Controller with ACPI Control Interface
The HIP6502 complements either an HIP6020 or an HIP6021 in ACPI-compliant designs for microprocessor and computer applications.
The IC integrates four linear controllers/
regulators, switching, monitoring and control functions into a 20-pin SOIC package.
One linear controller generates the 3.
3VDUAL/3.
3VSB voltage plane from the ATX supply’s 5VSB output, powering the south bridge and the PCI slots through an external pass
transistor during sleep states (S3, S4/S5).
A second
transistor is used to switch in the ATX 3.
3V output for operation during S0 and S1/S2 (active) operating stat...
